Just to let everyone know, Wii U has been updated to 4.0.2 now. I don't have a link with the news, nor do I know what 4.0.2 adds. I only know of it cause I just turned on my Wii U to get Zelda, Zelda 2 and Wii Sports Club.
Anyway, just passing on the info, hope it doesn't effect vWii Softmods or the possibility of a Wii U Softmod becoming an option.
Edit: info from Nintendo.com
